Fixed it for you. 

I don't think Breath of the Wild is going to reach those levels. 

It's gonna do so, no problem. But beating the CDi Zeldas on top of that will prove impossible, mah boi!

I have been predicting that BoTW will break records for about as long as I have been on these forums.  And yet, it is selling better than even I expected.  Look at this:

Q3 2017: 0.78m
Q3 2018: 0.96m
Q3 2019: 0.93m

How can it sell more in 2018 and 2019 (Q3), than it sold in 2017 (Q3)?  I have no explanation.  These sales numbers are like defying gravity or something.  All I can say is it will sell 25m+.  It's an unstoppable sales juggernaut.

Much larger install base in 2018, and many of the 2017 Switch owners picked the game up at launch.  The growing number of Switch owners is what keeps the game selling.  It's probably the Switch's signature title.  So, there aren't many people that are buying the game two years after they buy the hardware.   They're buying it with or soon after they get their Switch. 

Absolutely incredible performance and each of it's sales are well deserved!
The LoZ series was long overdue for a breakout like this.
Best game in the series and second best of all time! (Spoiler alert for the top 50 greatest games thread ;) )

20m is the floor for BOTW

Agreed. At this point selling 25mil is more likely then BOTW missing 20 mil.

It will keep consistent as long switch hardware is consistent. BOTW2 would only decrease a little. 3 to 4 million next FY with or without botw2.
Id say 23 to 25. A 25+ including wii U version.

Not going to bet against you, but I'm going with 19-20m

Opps, wrong thread.
